Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533632, here are decompositions:

  • 19 + 31533613 = 31533632
  • 61 + 31533571 = 31533632
  • 181 + 31533451 = 31533632
  • 223 + 31533409 = 31533632
  • 373 + 31533259 = 31533632
  • 499 + 31533133 = 31533632
  • 541 + 31533091 = 31533632
  • 619 + 31533013 = 31533632

Showing the first eight; more decompositions exist.
